LAMP-CHIMNEY HOLDER.

Specification of Letters Patent.

Patented Dec. 23, 1919.

Application filed March 4, 1919. Serial No. 280,620.

To all whom it may concern:

Be it known that I, EDWARD J. JONES, a subject of the King of Great Britain, res ding at Irma, in the Province of Alberta and Dominion of Canada, have invented new and useful Improvements in Lamp-Chimney Holders, of which the following is a specification.

This invention .relates to improvements in lamps, and has a special relation to means for holding the chimney upon the lamp burner in a manner to prevent its accidental misplacement. I

An object of the invention is to-provi'de simple and eflicient means carried by the lamp burner, which will engage the chimney so that a partial rotation of the latter will cause the chimney to be held securely in position, means being provided for limiting the amount of rotation when the chimney is being placed in position.

Other objects and advantages of the invention will appear as the following description is read in connection with the accompanying drawings.

In the drawings:

Figure 1 is a side elevation of a lamp with the invention applied thereto.

Fig. 2 is a detailed central vertical section taken through the burner and the lower portion of the chimney and illustrating the manner of engagement between the chimney and burner.

Fig. 3 is a top plan view of the burner.

Fig. 4: is a bottom view of the chimney, and

Fig. 5 is a detailed sectional view on the line 55 of Fig. 4, the lower end of the chimney being shown.

Referring to the drawings in detail, wherein like characters of reference denote corresponding parts, the lamp which may be of any preferred construction or design is illustrated at 10, the chimney is shown at 11 and the burner at 12.

The burner 12 may be of any type that is provided with the usual horizontally disposed flange 13, which extends outward around the outer periphery of the burner. It may also be provided with the usual vertical flange 14, which is divided into spring fingers, although this flange is not essential to the successful operation of the invention. V

The burner 12 is provided upon diametrispring retaining arms 15, which are spaced slightly above the upper face of the flange 13. The retaining arms 15 may, if desired, be formed of a single piece of spring wire, the central portion of which extends across the burner to provide means for securing one end of the arms 15, as indicated at 16. The wire is then formed into a loop 17, which connects with the adjacent end of each of the arms 15, so as to give the latter an outward and downward spring pressure. The opposite ends of the arms 15 terminate in diametrically disposed arms 18, the inner ends of which are secured to the burner.

The chimney 11 has extending inwardly from its base, diametrically located flanges 19. One end of these flanges is rounded, as shown at 20, for engagement beneath the loop end 17 of the spring arm 15. The flanges at their opposite ends are provided with a web 21, which extends upwardly at right angles to the flanges and is connected to the inner wall of the chimney. In addition to strengthening the flanges these webs act as a stop to limit the rotary movement of the chimney after the flanges have been inserted beneath the arms 15.

To place the chimney in position upon the burner, the flanges 19 are positioned be neath the arms 15 and the chimney rotated in a direction to cause the rounded ends of the flanges to enter beneath the arms 15 at the loop ends 17, the rotary movement of the chimney being continued until the loop engages the webs 21.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claims.

Having described the invention, what is claimed is:

1. A lamp embodying a burner provided with a horizontally disposed outwardly extending flange, retaining members comprising oppositely located arcuate shaped radially expansible retaining loops carried by and spaced upon each side of the burner and spaced above said flange, a chimney, an inwardly extending flange located upon the opposite sides of the base of the chimney for engagement between the burner flange and the arcuate shaped retaining member.

2. A lamp embodying a burner provided with a horizontally disposed outwardly extending flange, retaining members formed of a single piece of spring metal and including oppositely located arcuate shaped arms spaced above said flange, a spring loop located at one end of each of said arms to force the latter outwardly and downwardly, a chimney and inwardly extending flanges located upon opposite sides of the base of the chimney for engagement between the burner flange and the arcuate shaped arms.

3. A lamp embodying a burner provided with a horizontally disposed outwardly extending flange, retaining members embodying oppositely located arcuate shaped arms 15 cated upon opposite sides of the base of the 20 chimney for engagement between the burner flange and the arcuate shaped arms and a stop located at one end of each of said inwardly extending flanges.

In testimon whereof I aflix 111 si nature. 25

EDWARD J. JONES.
